ASP.NET Core News is the only weekly newsletter dedicated to ASP.NET Core. Whether you build Razor Pages, MVC applications, Web APIs, SignalR awesomeness, or anything else available on the ASP.NET Core platform, we've got you covered. Every Friday you will receive a weekly digest of the most interesting posts and articles from the last seven days.  

ASP.NET Core architect, David Fowler, supported by .NET Program Manager, Jon Galloway, will talk through their current thinking for the future of ASP.NET Core, beyond 2.0. Topics include the potential features of Kestrel, SignalR, and MVC as ASP.NET Core evolves beyond its current HTTP-only focus.

Integrating ASP.NET Web Forms and ASP.NET MVC 

Blazor Hybrid for Beginners
Join James Montemagno as he takes you on a journey of building your first Hybrid applications across iOS, Android, Mac, Windows, and Web with ASP.NET Core, Blazor, Blazor Hybrid, and .NET MAUI!  You will learn how to use Blazor Hybrid to blend desktop and mobile native client frameworks with .NET and Blazor.
In a Blazor Hybrid app, Razor components run natively on the device. Components render to an embedded Web View control through a local interop channel. Components don't run in the browser, and WebAssembly isn't involved. Razor components load and execute code quickly, and components have full access to the native capabilities of the device through the .NET platform. Component styles rendered in a Web View are platform dependent and may require you to account for rendering differences across platforms using custom stylesheets.
Blazor Hybrid support is built into the .NET Multi-platform App UI (.NET MAUI) framework. .NET MAUI includes the BlazorWebView control that permits rendering Razor components into an embedded Web View. By using .NET MAUI and Blazor together, you can reuse one set of web UI components across mobile, desktop, and web.
